1 ENVOLVING THE FUTURE OF SINGLE PILL COMBINATION IN ANTIHYPERTENSIVE THERAPHY Djanggan Sargowo Shangri-La, Surabaya - Sabtu, 23 Juni 2012

2 HYPERTENSION IS A PREVALENT DISEASE AFFECTING 1 BILLION PEOPLE TODAY Wolf-Maier et al. JAMA 2003;289:2363–9 Prevalence* of HTN (%) *Among persons aged 35 – 64 years old; age and sex adjusted HTN = BP 140/90 mmHg or on treatment

3 CLASSIFICATION OF BLOOD PRESSURE IN US ADULTS: JNC VII GUIDELINES BP categorySystolic (mmHg) Diastolic (mmHg) Normal<120and<80 Pre-hypertension120–139or80–89 Hypertension, stage 1 140–159or90–99 Hypertension, stage 2 160 or 100 Chobanian et al. JAMA 2003;289:2560 72

5 Lifestyle modifications Chobanian et al. JAMA 2003;289:2560–72 Not at goal BP* HTN without compelling indications HTN with compelling indications Stage 1 Thiazide-type diuretics for most. May consider ACE inhibitor, ARB, β-blocker, CCB, or combination Stage 2 Two-drug combination for most (usually including thiazide-type diuretic) If not at goal, optimise dosages or add additional drugs until goal BP is achieved. Consider consultation with hypertension specialist JNC VII: ALGORITHM FOR TREATMENT OF HYPERTENSION Drug(s) for the compelling indications Other antihypertensive drugs (diuretics, ACE inhibitor, ARB, β-blocker, CCB) as needed *BP goal <140/90 mmHg or <130/80 mmHg for those with diabetes or chronic kidney disease

6 Consider: BP level before treatment Absence or presence of TOD and risk factors 2-drug combination at low dose Choose between: Single agent at low dose If goal BP not achieved Previous agent at full dose Switch to different agent at low dose Previous combination at full dose Add a third drug at low dose If goal BP not achieved 2–3 drug combination 3-drug combination at effective doses ESH–ESC: ALGORITHM FOR TREATMENT OF HYPERTENSION ESH–ESC Guidelines. J Hypertens 2003;21:1779–86 Full-dose monotherapy TOD = target organ damage

9 Also Guidelines worldwide Acknowledge That Most Patients Need Combination Therapy to Achieve BP Goals Most patients with hypertension will require two or more antihypertensive medications to achieve their BP goals –When BP is > 20/10 mmHg above goal, consideration should be given to initiating therapy with two drugs Combination treatment should be considered as first choice when there is high CV risk –i.e., in individuals in whom BP is markedly above the hypertension threshold (> 20/10 mmHg), or associated with multiple risk factors sub-clinical organ damage, diabetes, renal or CV disease Chobanian et al. JAMA. 2003;289:2560–2572; Mancia et al. Eur Heart J. 2007;28:1462–1536; http://www.nice.org.uk/ download.aspx?o=CG034fullguideline (accessed January 2010); Ogihara et al. Hypertens Res. 2009;32:3–107. Many patients will require more than one drug to achieve adequate BP control –Pathophysiological reasoning suggests that adding an ACE-I/ARB to a CCB or a diuretic (or vice versa in the younger group) are logical combinations The use of two or three drugs in combination is often necessary to achieve the target BP control –A low dose of a diuretic should be included in this combination JNC VII ESH/ESC NICE The Japanese Society of Hypertension Committee for Guidelines for the Management of Hypertension 2009 JSH

10 MANAGEMENT OF HYPERTENSION: GUIDELINE RECOMMENDATIONS FOR COMBINING THERAPIES Multiple antihypertensive agents are needed to achieve BP goals European and US guidelines for combining antihypertensive therapies
11
11 BENEFITS OF FIXED-DOSE COMBINATION THERAPY Rationale for fixed-dose combinations (FDCs): efficacy; tolerability; compliance and persistence Beneficial impact of FDCs on compliance and persistence, and costs
12
12 RATIONALE FOR THE USE OF FIXED-DOSE COMBINATIONS: TOLERABILITY Low doses of two agents often result in fewer adverse events than high doses of one agent 1,2 –Physicians may accept less than optimal BP control to minimise adverse events Compound-specific adverse events can be attenuated, e.g. 1,2 –RAS blockers effectively blunt the metabolic effects of diuretics –RAS blockers may attenuate the oedema that is caused by calcium channel blockers (CCBs) 1 Sica. Drugs 2002;62:443 62; 2 Quan et al. Am J Cardiovasc Drugs 2006;6:103 13 FDC therapy may have an improved tolerability profile compared with its single-mechanism components 1,2
13
Single-Pill Combinations (SPC) significantly improve Compliance/Treatment adherence (~25%) Bangalore et al. Am J Med. 2007;120:713–719. p < 0.0001 Chronic disease (9 studies) Hypertension (4 studies) p < 0.0001 * With single-pill combination therapy vs free-drug regimens Relative reduction in non-compliance* (%) 30 20 10 0 13

Why Telmisartan + Amlodipine, because it Combines the best in class compounds – unique PK/PD evidence – in a single-pill combination Provides powerful and ‘smart’ BP reductions and high 24h BP control including patients with added-risk such as diabetes and obese Has a safety & tolerability profile similar to placebo regardless of the Telmisartan dose being used (40 mg or 80 mg) and Telmisartan 80mg is the CV preventive dose in ONTARGET. 36

42 THE CCB ARB TARGETS TWO KEY BP EFFECTOR PATHWAYS (1) Sympathetic nervous system (SNS) SNS activity → noradrenaline binds to α 1 -adrenergic receptors on vascular smooth muscle → vasoconstriction 1 SNS also stimulates renin secretion from the kidney, thereby activating the RAS 2 CCBs inhibit SNS-induced vasoconstriction by blocking influx of calcium ions (needed for contraction) through voltage-gated calcium channels → vasodilation 3,4 Other effects of CCBs: natriuresis; inhibition of aldosterone release; interference with angiotensin II-mediated vasoconstriction 4 1 Grassi.

43 THE CCB ARB TARGETS TWO KEY BP EFFECTOR PATHWAYS (2) Renin angiotensin system (RAS) Release of renin catalyses conversion of angiotensinogen into angiotensin I, which is converted by ACE to angiotensin II → –Vasoconstriction; increased aldosterone and sodium/water retention; SNS activation ARBs block the effects of angiotensin II by binding to AT 1 receptors –Arterial and venous dilation –Reduced SNS activity –Reduced secretion of aldosterone and increased secretion of sodium and water Mistry et al.
